I know for certain that there are 72MHz ARM chips out there that sleep well below 40mA (I think in the 1mA range). I wonder what keeps this one so hungry while asleep. The NXP 24xx chips have been around for a while, though. They're extremely capable (USB host capabilities and such) but might lag a little behind the most recent speedy embedded ARM chips in terms of efficiency.
